(cat /tmp/header; date; uptime;cat - /tmp/signature) | \ mail -s 'A case where cat is needed' kclug(a)kclug.org The ( ) pair spawns s sub-shell which allows multiple commands to share the same input, output, and error streams. In this case I used 'date' and 'uptime' along with a second 'cat'. The second 'cat' reads from stdin (standard in) till it sees EOF (End Of File <Control-D>) and then follows that with the /tmp/signature file. Stdout of all those commands is sent to stdin of the 'mail' command.

Cups - lpoptions - I Dunno?!?!

So, I'm finishing up my conversion from SCO UNIX 3.2 / Keypoint to Linux. Got the data off the old server and onto the new server. Had the VAR setup Keypoint software and everything is working on that end. I still have a few hiccups that I'm working on and could use some help. 1.) The Keypoint software requires WYSE 60 emulation to work properly. We are using SecureCRT for Windows workstation clients and all works well however, the ANSI characters are not the same as they were in the old serial terminals they were using. Dashes or hyphens that are used in the program for simple menus are now O's and the like. Is there a way (or setting) to get the proper characters back? 2.) The biggest problem! They print from Keypoint using an Okidata ML320 9-pin printer which is connected to the server directly through lp0. The software prints everything fine but the printer prints in LQ mode instead of Draft mode. I need this printer to print in Draft mode for speed reasons. All settings on the front panel of the printer are overridden by cups (or lp?) at print time so simply selecting "Draft" from the printer's front panel does not work. On the old system, the printer would print everything in Draft mode and all was good. They have one certain page that they print that they would select a CPI of 17 (instead of 10) to get everything on the page. This no longer works. If I select a CPI of 17 on the front panel, then try to print this page, the CPI is changed back to 10 by the server. If I add "raw=true" in /etc/cups/lpoptions, the printer will print in Draft mode but does not handle page length properly. It feels like I need to add a "Draft" option to lpoptions but I have not found any reference to setting print quality in lpoptions on the net so I'm stuck. Comments? Please help and thanks a bunch! -- RtX... Ty Unes - Overland Park, Ks. riverty(a)gmail.com

Linux / Sco Stuff.
by RtX 13 Dec '06

13 Dec '06

I have a client that has a very old 486 server running SCO UNIX 3.2. My job is to get the data off of this machine and get it on to a Linux machine. The problem here is that the 486 is ISA bus only. It does not have an IDE bus, main system HDD is SCSI (328MB). No network option, tape backup drive does not work either. I want to add a second SCSI disk to the system formatted in DOS FAT16, copy the data over to this drive, and then copy the data back on to the new Linux server. I am having no joy getting this SCO 3.2 system to mount the drive. I don't know how. I mean I know how to mount drives in Linux and AIX but I fail to get this done in SCO. Could anyone please advise me on the steps needed to get this drive mounted in SCO? -- RtX... Ty Unes - Overland Park, Ks. riverty(a)gmail.com

Well good luck in the fight to remove old hardware and more specifically SCO. Yet more reason that SCO blows goats and why you can't get too far behind the times w/ a proprietary OS. I bet if you contacted SCO, they'd sell you some pkg to give full DOS support, a tool to format a drive to work in SCO, or even network support. The key is they'd sell you something to get your data back off their incompatible old piece of crap OS. Good luck with Debian and may your nightmares be few. Many server apps I'm seeing lately have support for at least RedHat, so there is hope. >-----Original Message----- >From: On Behalf Of RtX >Sent: Sunday, December 10, 2006 11:43 AM > >Job is done.

I have NEVER seen a 486 with USB ports. I imagine if you had one with a PCI port, you could add a USB PCI Card. That adapter you sent a link to is for what looks like 68-pin SCSI, and his drive is probably DB25 or 50-pin or lord knows what else at that age. It's a 328MB SCSI drive. I don't know if I've even seen a SCSI drive at less than 1 or 2 GB and still knew what it was. We're talking ancient freakin history here.

And after the "project " is do n e, either keep it in your toolset or use it to wipe and format ALL the stack of SCSI drives in your collection- possibly even using them for "Offsite Data Buckets" of data to be safe deposit boxed etc. Oren
